General Legal (YC26) just became the first law firm in the world to be hired by an AI agent. We won't be the last.
Last week, one of our clients - an agentic AI start-up - suggested that we start marketing our law firm to agents, not just to humans. We considered it... then, we set up a profile on rentahuman.ai and waited. After 6 days of weird crypto spam from agents who did not seem interested or empowered to hire a lawyer, an agent actually looking for legal help on behalf of a human sent an inquiry. Then, it "signed" an engagement letter on behalf of the human, and we counter-signed (via human.. how boring) even though they were asking us to review a contract that we don't currently support.
Agent-only deal I guess?
This unscripted client inquiry happened to arrive from an agent instead of a person, a little taste of the future. What we experienced on a small scale is part of a shift that market researchers are already tracking at the level of the broader economy. Agentic commerce, commercial activity initiated or completed by AI agents acting on behalf of humans rather than the humans doing it directly, is projected to become the default way businesses transact with each other. Gartner's top strategic prediction for 2026 puts a number on it: by 2028, 90% of all B2B purchases will be intermediated by AI agents, routing more than $15 trillion through automated, machine-to-machine exchanges.
Sure, we aren't quite there yet. The same research found that only about 3% of transactions today involve an AI agent, however, 89% of merchants are already preparing for the agentic commerce age. Professional services like legal work sit right in the middle of that shift. We're eager to be the first law firm hired by an agent on a client's behalf.

TL:DR: General Legal became the first law firm hired by an AI agent acting on behalf of a human client, after setting up a profile on the AI-agent marketplace rentahuman.ai and fielding six days of unrelated spam before a legitimate inquiry arrived. The agent signed the engagement letter on the client's behalf, and a General Legal partner countersigned for the firm. It's a small moment, but it lines up with a much bigger shift already underway. Gartner predicts that by 2028, 90% of all B2B purchases will be intermediated by AI agents, moving more than $15 trillion through machine-to-machine exchanges, even though only about 3% of transactions involve an agent today.
FAQs
Did an AI agent actually hire General Legal, or was this a demo?
It was a real, unscripted client inquiry. An AI agent working on behalf of a human client found General Legal through rentahuman.ai, signed an engagement letter on the client's behalf, and a General Legal partner countersigned for the firm.
What is rentahuman.ai?
Rentahuman.ai is a marketplace built for AI agents to find and hire humans or human-run businesses for tasks the agents can't do themselves. General Legal set up a profile there at a client's suggestion.
Did the agent actually need the legal help it was asking for?
The inquiry was for a type of contract review General Legal doesn't currently support, so the firm couldn't take on the matter as requested. It's an early sign that agent-driven client intake still has rough edges.
Is it common for AI agents to make B2B purchases or hire services right now?
Not yet, but that's changing fast. Only about 3% of transactions today involve an AI agent, even though 89% of merchants are already preparing for agentic commerce, and Gartner projects that 90% of B2B purchases will be intermediated by AI agents by 2028.
Is General Legal actually the first law firm hired by an AI agent?
That's General Legal's own claim based on this engagement. Given how early and rare agent-initiated B2B transactions still are, it's a plausible first, though not one that's independently verified by a third party.
